That's precisely why MUNNABHAI M.B.B.S. works! Munnabhai lives with his gang in the by lanes of a washer man in Mumbai, takes pride in being a 'social worker'they actually settle 'financial disputes' through bossing around and enjoys his booze, babes, brawls? Munna's father, Hari Prasad Sharma , an upright, moralistic man, believes that his son is actually a doctor running a charity hospital. Every year, when his parents arrive, Munna and his gang bathe, shave, don white coats and stethoscopes and pretend to be diligent doctors. But the clever charade falls apart. Hari Prasad Sharma runs into an old friend, Dr. Asthana, who has a daughter called Suman . The two decide that their children, both doctors, would make a perfect match. Munna tries hard to save the situation, but his father discovers the truth. And all hell breaks loose.
